vIMPRovru) BRICK-meme.

use my invention, I will proceed to describe it.

My invention relates to brick-machines, and consists in certain'improvements on the machine for which Letters Patent, No. 79,362, and dated J une 30, 1868, were granted to me. These limprovements are for the pur- -pose of giving an intermittent motion to the horiontally-rotating mould-wheel, and also for giving a seoond pressure to the brick, by means of certain novel mechanical devices.-

In the drawings Figure 1 is a top plan view, and Figure 2 is a vertical section on the line .fc-x of Inv constructing my machine, I mount in a strong frame, A, a horizontally-rotating mould-wheel, B, having a series of moulds, G, and each provided with a follower, a, as shown in figs'. 1 and 2.

On the periphery of the mould-wheel B, I place a series of cogs, b, so that there may be acog immediately opposite each mould, as shown in fig. 1, to engage with an arm, D, arranged to operate in a pecu- It is made long, as shown in iig. l, with its rear end running through guides f, with curved faces, and fastened on top Vof an upright, c, and with its front end provided with a head,

g, shaped as shown in fig. l, so as to engage easily with the oogs b, and having a pin on its under side which moves easily about the oblong groove h, for the purpose of guiding the movement of its front end, which groove h is shaped as shown in the same ligure.

Over the arm D, and nearest to its rear end, I mount, in the frame of the machine, a vertical shaft, i, and to this shaft, immediately above the arm D, I attach a cam, E, provided with a pin, j, which enters and plays, with a reciprocating motion, in a groove, k, set at right angles to the length. of the arm D, and being in andA Hush with the upper surface of two hat arms, Z, at-` tached on eachv side of the arm D, and arranged to slide on uprights c, and having vertical projections m for the cam E to bear against in rotating, as shown in iig; 1.

The vertical shaft i has attached to it a bevel-gear, connecting it with a corresponding gear on Athe horizontal shaft F, mounted in the frame, and provided .with a driving-wheel, as shown in iig. 1.

By the use of these mechanical devices, thus con. structed and arranged, 1 give an intermittent rotatory motion to the mould-wheel B, as will beseen.'

When the arm D has engaged with a cog,b, the parts are in the position as shown in fig. 1.

As the driving-wheel, through the bevel-gear on the shafts F and i, continues the motion of the cam. E, in the `direction of the red arrow, the movement of the pin in the slot k draws the arm D back, carrying forward the mould-wheel B till the pin in the head of the front end of the arm D reaches the rear end of the groove h, when the cam E strikes against the` outer vertical projection m, throws the front end of the arm D back, discngaging it from the cog on the wheel B, and'leaving the wheel stationary, after having been moved just far enough for another cog to occupy the same place as the one just released did when the movement commenced. As the cam E, however, continues its motion, the .pin in the groove k now carries the arm D forward till the pin in its head reaches the front end of the grooveh, when the cam E bears against the inner vertical projection m, which throws the-front end of the arm D forward, when it engages a cog, b, as before, and another movement is given to the wheelB.

While this is being done, the clay is carried by the feed-rolls G and a spiral screw, not shown, but fully explained in my former patent, already mentioned, to l the' moulds G, in the wheel B.

The feed-rolls and spiral screw are operated by the shaft F and gearing H, all mounted in the anne, as shown in fig. l.

' The movements of the arm D are so timed as to leave the wheel B stationary every time a mould, O, Y

filled with clay, comes immediately under the plunger I, which is then moved vertically downward by a pin,

attached toa small crank on the end of `the shaft F, operating in a curved slot or groove, 1r, in the shank 'of the plunger I, as shown in gs. 1 and 2.

The plunger I ceases pressing, and is elevated by the same means and at the same time that the wheel I B moves forward, and so at each operation.

Atthe same time that the movements of the mould,

wheel B and plunger I are arranged so as to give oneI its face,` provided with an elliptical-shaped groove, q,

as shown in iig. 2.

Between the disk K and the bearing of the shaft J, I place a vertical rod, L, having its upper end slotted so as to move vertically on the shaft J, and also proi videdl with a pin to travel in the groove q.

The lower end ofthe rod L, I hinge to a lever, M,

pivoted at'fr', i`n theb'ase of the frame A, as shown in` The loose end s is arranged so that every time the by the lever M, the hinged end of which is forced down bythe rod L, as shown in iig. 2, and its outerend, s, is pressed against the follower c at the same time that the plunger I descends against the brick in the mould,

then directly under it.

The wheel B, in its rotation, carries the brick thus pressed in the moulds till the followers a are raised by the inclined plane 'P, when the brick can be -removed from the wheel.

By this construction and arrangement of the novel mechanical devices, as herein described, I am able to manufacture brick with a smooth upper` and lower sur-Y face, by giving them a top and bottom pressure, which double pressure also makes them of a -more uniform density throughout.

Having thus described my invention,

What I claim, is-

1. The combination of devices, constructedl and arranged substantially as herein described, for giving an intermittent rotating motion to the horizontal mouldwheel B, as and for the purpose herein set forth.

2. The cross-beam N, or its equivalent, in combination with 'the follower al and lever M, with the mechanical devices for operating it, all constructed and arranged to operate substantially as described, and for the purpose set forth. y

3. rlhe construction and arrangement of the me- .chanical devices, substantially as herein described, byl

which a top pressure is'given to one brick bythe plunger I, and a bottom pressure to another by the lever M, simultaneously, at diiferent points in the machine, as set forth.
